It has already become known that specific phenylsulphonyl-imidazoles and phenylsulphonyl-benzimidazoles have fungicidal properties (cf. EP-A 0 238 824 and WO 97-06 171). Thus, 1-(2-methyl-5-nitro-phenylsulphonyl)-benzotriazole, 2-methyl-1-(2-methyl-5-nitro-phenylsulphonyl)-imidazole and 1-(2-methyl-5-nitro-phenylsulphonyl)-2-chloro-6,6-difluoro-[,1,3]-dioxolo-[4,5-f]-benzimidazole can be used for controlling fungi. The activity of these substances is good but is unsatisfactory in some cases at low application rates.

In this formula, R¹, R² and X preferably have those meanings which have already been mentioned in connection with the description of the substances, according to the invention, of formula (I) as being preferred for the substituents.

The compounds of the formula (II) may be present in the following two tautomeric forms.

If the molecular unit

is symmetrical, the tautomeric forms are identical. In the reaction, according to the invention, with nitrobenzenesulphonyl halides of the formula (III), only one specific end product of the formula (I) is thus formed in each case, and is formed independently of which of the two tautomeric forms reacts.

If the molecular unit

is asymmetrical, the two tautomeric forms are not identical. In the reaction, according to the invention, with nitrobenzene-sulphonyl halides of the formula (III), end products of the formula (I) which are derived from the tautomeric forms of the formulae (IIa) and/or (IIb) can thus form. If both tautomers react, end products of the formula (I) are obtained in the form of mixtures.

The imidazole derivatives of the formula (II) are known or can be prepared by known methods (cf. WO 97-06171, Chem. Ber. 85, (1952) 1012-1020), J. Med. Chem. 34 (1991), 1110-1116 and J. Chem. Soc. 1965, 3017-3021).

The nitrobenzene-sulphonyl halides furthermore required as starting materials for carrying out the process according to the invention are generally defined by the formula (III). In this formula, R³ preferably has those meanings which have already been mentioned in connection with the description of the substances, according to the invention, of the formula (I) as being preferred for these substituents. Hal also preferably represents chlorine or bromine.

The nitrobenzene-sulphonyl halides of the formula (III) are known or can be prepared by known methods (cf. EP-A 0 238 824).

When carrying out the process according to the invention, the reaction temperatures can be varied within a relatively large range. In general, temperatures betwen 0° C. and 150° C., preferably temperatures between 10° C. and 120° C., are employed.

The process according to the invention is generally carried out under atmospheric pressure. However, it is also possible to employ superatmospheric or reduced pressure.

When the process according to the invention is carried out, in general 1 to 1.5 mol of nitrobenzene-sulphonyl halide of the formula (III) and an equivalent amount or an excess of acid acceptor are used per 1 mol of imidazole derivative of the formula (II). The working up is effected by customary methods. In general, water is added to the reaction mixture, the mixture formed is extracted several times with an organic solvent slightly soluble in water, and the combined organic phases are dried and evaporated down. The substances obtained can optionally be purified by customary methods, such as chromatography or recrystallization.

The active substances according to the invention are suitable for controlling vegetable pests and can therefore be used for controlling undesired microorganisms, such as fungi or bacteria, in crop protection and in material protection.

The active substances according to the invention are also suitable for increasing the harvest yield. In addition, they have low toxicity and possess good plant tolerance.

Depending on their respective physical and/or chemical properties, the active substances can be converted into the customary formulations, such as solutions, emulsions, suspensions, powders, foams, pastes, granules, aerosols, very finely encapsulated forms in polymeric substances and in coating materials for seed and ULV cold and warm mist formulations.

These formulations are prepared in a known manner, for example by mixing the active substances with extenders, that is to say liquid solvents, liquefied gases under pressure and/or solid carriers, optionally with the use of surfactants, that is to say emulsifiers and/or dispersants and/or form-producing compositions. In the case of the use of water as an extender, for example, organic solvents may also be used as auxiliary solvents. Suitable liquid solvents are essentially: aromatics, such as xylene, toluene or alkylnaphthalenes, chlorinated aromatics or chlorinated aliphatic hydrocarbons, such as chlorobenzenes, chloroethylenes or methylene chloride, aliphatic hydrocarbons, such as cyclohexane or paraffins, e.g. mineral oil fractions, alcohols such as butanol or glycol, and their ethers and esters, ketones, such as acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone, strongly polar solvents, such as dimethylformamide and dimethyl sulphoxide, and water. Liquefied gaseous extenders or carriers are those liquids which are gaseous at normal temperature and under normal pressure, for example aerosol propellants, such as halogenohydrocarbons and butane, propane, nitrogen and carbon dioxide. Suitable solid carriers are: for example, crushed natural minerals, such as kaolins, aluminas, talc, chalk, quartz, attapulgite, montmorillonite or diatomaceous earth, and crushed synthetic minerals, such as finely divided silica, alumina and silicates. Suitable solid carriers for granules are: for example, crushed and fractionated natural minerals, such as calcite, marble, pumice, sepiolite, dolomite, and synthetic granules of inorganic and organic powders and granules of organic material, such as sawdust, coconut shells, maize cobs and tobacco stems. Suitable emulsifiers and/or form-producing compositions are: for example, nonionic and anionic emulsifiers, such as polyoxyethylene fatty acid esters, polyoxyethylene fatty alcohol ethers, e.g. alkylaryl polyglycol ethers, alkylsulphonates, alkylsulphates, arylsulphonates and protein hydrolysis products. Suitable dispersants are: for example, ligninsulphite waste liquors and methylcellulose.

Adherents, such as carboxymethylcellulose, natural and synthetic pulverulent, granular or latex-like polymers may be used in the formulations, such as gum arabic, polyvinyl alcohol, polyvinyl acetate and natural phospholipids, such as kephalins and lecithins, and synthetic phospholipids. Further additives may be mineral and vegetable oils.

Colorants, such as inorganic pigments, e.g. iron oxide, titanium oxide, Prussian blue, and organic dyes, such as alizarin, azo and metal phthalocyanine dyes, and trace nutrients, such as salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc, may be used.

The formulations contain in general between 0.1 and 95 percent by weight of active substance, preferably between 0.5 and 90%.

Depending on their respective physical and/or chemical properties, the active substances can be converted into the customary formulations, such as solutions, emulsions, suspensions, powders, foams, pastes, granules, aerosols, very finely encapsulated forms in polymeric substances and in coating materials for seed, and ULV cold mist and warm mist formulations.

The active substances according to the invention can be used, as such or in their formulations, also as a mixture with known fungicides, bactericides, acaricides, nematicides or insecticides, in order, for example, to broaden the action spectrum or to prevent the development of resistance. In many cases, synergistic effects are obtained, i.e. the activity of the mixture is greater than the activity of the individual components.

A mixture with other known active substances, such as herbicides, or with fertilizers and growth regulators, is also possible.

The active substances can be used as such, in the form of their formulations or the use forms prepared therefrom, such as ready-to-use solutions, suspensions, wettable powders, pastes, soluble powders, dusting agents and granules. They are used in a customary manner, for example by pouring, spraying, atomizing, broadcasting, dusting, foam application, brushing, etc. It is also possible to apply the active substances by the Ultra-Low-Volume method or to inject the active substance formulation or the active substance itself into the soil. The seed of the plants may also be treated.

When the active substances according to the invention are used as fungicides, the application rate may be varied within a relatively large range, depending on the method of application. In the treatment of plant parts, the application rates of active substance are in general between 0.1 and 10,000 g/ha, preferably between 10 and 1000 g/ha. In the treatment of seed, the application rates of active substance are in general between 0.001 and 50 g per kilogram of seed, preferably between 0.01 and 10 g per kilogram of seed. In the treatment of the soil, the application rates of active substance are in general between 0.1 and 10,000 g/ha, preferably between 1 and 5000 g/ha.

The compositions used for protecting technical materials contain the active substances in general in an amount of 1 to 95%, preferably of 10 to 75%.

The use concentrations of the active substances according to the invention depend on the type and occurrence of the microorganisms to be controlled and on the composition of the material to be protected. The optimal amount for use can be determined by test series. In general, the use concentrations are in the range from 0.001 to 5% by weight, preferably from 0.05 to 1.0% by weight, based on the material to be protected.

The activity and the action spectrum of the active substances to be used according to the invention in material protection or of the compositions, concentrates or very generally formulations which can be prepared therefrom can be increased if optionally further antimicrobial compounds, fungicides, bactericides, herbicides, insecticides or other active substances are added for increasing the action spectrum or achieving special effects, such as, for example, additional protection from insects. These mixtures may have a broader action spectrum than the compounds according to the invention.

Even when used against animal pests, the substances according to the invention may be present as a mixture with synergistic agents in commercial formulations and in the use forms prepared from these formulations. Synergistic agents are compounds by means of which the action of the active substances is increased without the added synergistic agent itself having to be actively effective.

The active substance content of the use forms prepared from the commercial formulations may vary within wide ranges. The active substance concentration of the use forms may be from 0.0000001 to 95% by weight of active substance, preferably between 0.0001 and 1% by weight.

Application is effected in a customary manner adapted to one of the use forms.

The preparation and use of substances according to the invention are illustrated by the following examples.

PREPARATION EXAMPLES Example 1

1.4 g (10 mmol) of potassium carbonate are added to a solution of 1.7 g (7 mmol) of 2,5-dibromo-4-methyl-1H-imidazole in 40 ml of acetonitrile at room temperature. The mixture is stirred for 10 minutes at room temperature, and 1.7 g (7 mmol) of 2-methyl-5-nitro-benzenesulphonyl chloride are then added. Stirring is carried out for a further 20 hours at room temperature and the reaction mixture is then poured onto 100 ml of water. The mixture formed is extracted twice with 50 ml of diethylether in each case. The combined organic phases are dried over sodium sulphate and then evaporated down under reduced pressure. The remaining residue is chromatographed on silica gel using methylene chloride as mobile phase. 1.6 g (51% of theory) of 1-(2-methyl-4-nitro-benzenesulphonyl)-2,4-dibromo-5-methyl-1H-imidazole are obtained in this manner in the form of a colourless solid substance of melting point 187 to 189° C.

To demonstrate the activity against fungi, the minimum inhibitory concentrations (MIC values) of compounds according to the invention are determined.

Active substances according to the invention are added, in concentrations of 0.1 mg/l to 5000 mg/l to an agar which is prepared using malt extract. Solidification of the agar is followed by contamination with pure cultures of test organisms. After storage for two weeks at 27° C. and 60 to 70% relative humidity, the minimum inhibitory concentration (MIC value) is determined. The MIC value characterizes the lowest concentration of active substance at which there is no growth at all of the microbe species used.

Active substances, test organisms and MIC values are shown in the table below.
